A data center includes: a server including a control plane; a data plane that is configured to receive network connection information from the control plane; and a storage group including a plurality of first storage devices. The data plane may be configured to set connections between the server and the plurality of first storage devices based on the network connection information corresponding to each first storage device of the plurality of first storage devices.

Data center

The present invention relates to a method for controlling hand-over in a drone network. A method for controlling hand-over in a drone network that is established by a plurality of drones that constitute a formation, and controlled by a ground control station (GCS) that controls the location, configuration and mobility of each of the plurality of drones according to the present invention includes a phase via which the GCS predicts, based on previously stored control information, a drone that is to be newly deployed or transferred from another formation and allocates network connection information to the drone thus predicted; a phase via which the GCS generates a virtual routing table including the drone that is thus predicted to be deployed or transferred; a phase via which the GCS, upon actual deploying or transferring the predicted drone, changes the virtual routing table into an actual routing table; and a phase via which the GCS, upon the drone thus deployed or transferred transmitting a control message of the formation routing protocol, calibrates and optimizes the routing table.

Method for controlling hand-over in drone network

A method and an electronic device for controlling a topology are provided. The method includes forming a star topology by directly connecting the electronic device to at least one node, and transmitting and receiving signals with neighboring nodes including the at least one node and determining whether to form the star topology or an extended star topology with the neighboring nodes based on a result of the transmitting and receiving, wherein the star topology is a topology in which the electronic device is directly connected to the neighboring nodes, and wherein the extended star topology is a topology in which the electronic device is directly connected to the neighboring nodes via an already connected node.

Method and apparatus for controlling topology

An image encoding apparatus and method and an image decoding apparatus and method are disclosed. The image encoding method may include extracting a ROI from an input image, determining a compression rate of a remaining region excluding the ROI of the image based on a network state between the image transmitting apparatus and the image receiving apparatus, and encoding the remaining region based on the compression rate.
